Confirmed with a turbo rebuilder is20 Wastegate and is38 are interchangeable and the same unit.
They are different. The rod on the IS20 is longer.
On my GTI I am running IS38 with a IS20 waist gate so you can get the one to work with the other.
Hmmm so they work with each other but are different? I guess that's good enough for me!
Does the Wastegate still need to be adjusted on vagcom if I reuse my is20 Wastegate vs a brand new one for the is38?
With the IS20 waistgate I didnt need to do adjustment but in my past experience with both you might need to loosen or tighten it some.
Ok so just to confirm reusing old stock is20 Wastegate on new is38 turbo no need to adjust. Only need to adjust for brand new is38 and new is38 Wastegate got it!
Thanks for the help George amazing as always!
